===Channels list===

<br />
List of channels, their names, designation and description - clicking on an entry in this list determines which channel is configured at the moment. Settings for each channel are unique and do not depend on the configuration of other channels, except for resolution settings and color space for video capture card, which must be the same for each channel on a particular processor board.
<br />

===Channel parameters settings===

While configuring channels parameters it’s necessary to indicate the [[#Channel purpose|channel purpose]] and the [[#Source type|type of source]] for receiving the data.

====Channel purpose====

'''Channel purpose''' – is a setting which is needed to determine the operation mode of the channel.
<br />
:* live - the mode in which the recognition of number plates is not made;
:* demo - the mode in which the recognition of number plates is made, all possible alerts are displayed to the operator;
:* flow (path) – the mode in which the recognition of number plates are made, though, only alarm alerts are shown to the operator.

====Source type====

'''Source type''' - is a setting which determines how the video flow and the parameters of its transmission are transferred to the system.

===Channel name and description=== 

The channel name and its description are intended to facilitate the work of operators. For example, specifying the location of the camera in future could greatly accelerate processing of information by the operator; since he will not have to guess from which camera the image was received.

===Viewport’s selection===

When choosing the '''viewport''' for display on the "Live" tab one should pay attention to the following notation:
<br />
:* gray '''viewport''' - free, can be selected to display the video flow;
:* green '''viewport''' - selected at the moment to display the video flow;
:* red '''viewport''' - is in use by another channel, can not be selected to display the video flow.

If the setting is done correctly, then the following changes will occur on the tab “Channel Settings” (fig. ''Channel settings. Configured channel''):
<br />
:* the name of the channel, the motion direction and its purpose (in case it is specified)  will appear in the upper right corner; 
:* video flow from selected source will appear in viewport for displaying video;
:* channel description and its assignment will appear in the channel list.

===Brightness===

This setting provides software brightness control of the frame that is being recognized. It is recommended to adjust this setting if you know that the object of observation will have a non-standard lighting (shaded or highlighted).

<br />
<font color="#334F9C"> '''''Attention!'''''</font>
----
<font size="2" color="grey">'' 
Changes of this setting are not visible for an operator; they can be tracked back by frames in the "Events" tab.''</font>

===Contrast===

This setting provides software contrast control of the frame that is being recognized.

<br />
<font color="#334F9C"> '''''Attention!'''''</font>
----
<font size="2" color="grey">'' 
Changes of this setting are not visible for an operator; they can be tracked back by frames in the "Events" tab''</font>

===Threshold===

This setting determines capturing sensitivity. Contrast between the color of alphanumeric signs and license plates depends on the brightness and contrast of the incoming frame. Reducing this setting enables better recognition of dirty plates; increasing this setting allows recognition of clean plates only.  Recommended value — 21.
